Finite element simulation for microclimate normalization at the crane operator workplace

Abstract

The object of the study is the cabins of technological machines, where an unfavorable microclimate is observed. The method of mathematical and computer modeling used in the study is relevant and allows significantly speed up the design process due to the transition from a large number of field tests to virtual numerical experiments. The adaptation of the known mathematical models of thermal radiation and a model of a continuous medium based on the Navier-Stokes and heat transfer equations to the solution of the problem of determining the thermodynamic parameters in the cabins of technological machines has been carried out. The methodology for calculating and selecting the main equipment of the climatic system of the crane cabins has been clarified based on the developed finite element 3D models of the cabins. In addition, thermal protection equipment was used to reduce the load on the climate system. The using of modeling permit significantly speeds up the design process.
